Re: Perform Varying Statement

[Howard Weatherly <hweatherly@xxxxxxxxxxxx>]

Chris,

In your example, the compiler could easily be confused because of the
positionling of the scope delimeter, end-perform refers to the perform
immediatly preceeding and would leave the initial perform un-terminated until it
found a period or an end-perform. Each in-line perform must be terminated with a
scope delimiter while an out-of-line perform does not. "BUT" the compiler can
get confused! and is most likely pairing the end-perform with the perform add
and then notices that the perform varying is un-terminated. And since I am
answering then reading :-), the seu editor is even less adapt at parsing! This
does work, I have done it.
